Can I use an external load balancer with mpiexec by providing a single hostname in hosts file with, optionally, some large number for host rank, and putting load balancer listening on that hostname and forwarding connections to the actual hosts? I am trying to achieve autoscaling (load balancer tracks liveness of hosts and spins up new ones on demand). _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
